Guimaraens (Port. Guimaraes), a town of Portugal, in the province of Minho, between the Ave and Vizella, 32 m. N. E. of Oporto; pop. about 8,000. The town stands on a gentle slope, nearly surrounded by an amphitheatre of hills, is generally well built, and has several good streets and public squares. It is fortified, and contains an ancient castle, with square towers at the angles and in the middle of each side. The keep, which is in the centre, is entered at mid-height by a wooden bridge. Among the public buildings are a tine collegiate church called the cathedral, a Dominican convent of the 14th century, and a hospital. There are manufactories of cutlery, iron ware, paper, leather, cotton, and linen; and large quantities of plums and figs are exported. Near by are hot sulphur springs, which have been frequented for centuries. Guimaraens is said to have been founded by Celts about 500
B. 0. Henry of Burgundy made it the capital of Portugal in the beginning of the 12th century. Here began the reign of King Wamba, which is the proverbial expression for chronological indefiniteness.
